To all whom it may concern* Be 1t known that l, CHARLES Srino, a citizen of the United States, residing at New York, county of. 'New York, and State or" York, have invented certain new and 1 New useful Improvements m tien, reference being com anying` drawing'.

Tlliis invention relates ment, and particularly to a key lever and lever coperatively connected to artuate the type bar. y.

The invention -has for an object to provide a novel and improved construction oi' key lever having an angular extension therefrom by which it ispivoted, and a rocker face in contact with a cooperating; lever Aconnected with a type bar.

A- further object of. the invention isto pro- 4vide a guiding and supporting plate having a slot in which both the key lever and type lever are mounted so that they are constantly retained in parallelism during their travel to secure an easy and accurate movement of the parts. A.

Another object of the invention is to provide upon the angular extension of the key lever a curved rocker face which. bears agains the type lever above the pivot thereof so that vin the depression of the key lever this rest and to continue-an face engages the type lever first at. the highest point above its pivot, andin the rocking movement the.point oit Contact descends until the lower ortion ofI the extension is reached when tile type is in contact with the platen. 'y This secures the desired leverage to overcome the inertia of the type bar when' at even upwardmovement thereof requiring the minimum power and also. the minimum extent ot' travel of the key lever for that purpose. Other 'and further objects and advantages of the invention will be hereinafter set iorth and ap ended claims.

Specification of Letters Patent. Apl'aicanbn mea December 27, 1907.

` '.lype-Bar Move- .me/nts, of which the 'following is a specifica d had therein to the acto a type bar nxovei the novel features thereof defined by the W Patented April 2o, 19o9. sei-iai No. 408,237.

r The numeral l() designates the key level g which may be of any desired construction or conti gu ration and is provided at its front portion Awith the usual key 11 and extends through a slot in the guide plate 12 carried by the frame ol themachinc in the ordinary manner. The rear of this key lever is provided with an angularly disposed extension I which in thefyiresoni: illustration is at sub stantially a right angle to the body of the lever, and is provided at its upper end with a pivotal commotion, the samev being here shown in the forni ol a hook 14 adapted to engage the supporti-ng fiange 16 of the sup porting' and guiding plate 15 shown in Fig. 4. The outer face ofy this extension is curved as at 1.7 upon a suitable are to provide a rocking motion thereof inthe oscillation ofthe lever upon its pivot. In-order to retain this lever in con tact with the flange 16a suitable guard piece 18 is disposed above the samer` form of key lever is ada control any desired mec ianism brought into contact therewith, and inits application to a typewriter the rocker face 17 is disposed in contact with the type lever 19 which is slotted at its lower end 20 and mounted upon an angle plate 2] carried by the frame of the machine and extending across the same to' accommodate a series of levers. The lever is located in the slot 22 of the supporting and guide plate 15u and both the key and type levers being'Y -of `plate material are'disposed in the same slot to travel therein at all times and arethus'iiirmly held in alinernent. The lever is normally drawn toward the front ol the machine by means of the ,tension spring 23 extendingy therefrom lto thewflqange plate 21. 'Pheupper end 24 connected by a ligament 25 witi the` type bar 26.` `'This barmay be 1of anydesired character and is here shown mounted upon a supporting plate or sector 27 and provided wit 1 thc connecting plate 28 for the ligament. hen at rest the bar is disposed ,upon the usual suplport 29 and in its upward travel engages tie frontfac'e o-f the plate 30 also mounted to travel in the usual manner. The key and t pe levers are duplicated to eorrespond'wit 1 the typ'e barsor other parts to be actuated and are all supported by the comted to actuate and frame, only illustrated. A

In the operation of the invention the posi#` of the.ty`e lever is This mon plates extending across the machine one set of 'sind bars being herev Vile tion ol the parts when at rest is shown ink face secures a smooth and easy action with the leverage starting at a point removed from the pivot of the type lever and advanci-ng toward -said pivot at the closeol' the action at which time the type bar is in contact with the platen, as shown in Fig. 3. The construction of the key lever having a pivot at the upper portion of its extension provides for the maximum leverage between the parts with a minimum travel at the ke end of the lever thus producing the smoot i and easy action with a short stroke most desirable in typewriting machines and other mechanism actuated from key levers.- The coperation of the. typelever with this extension' of the key lever provides a convenient .structure for conveying the oscillatory motion of the key lever to the type bar in rising from its point'of rest int oA contact with the platen. The supporting and guard plate having the sei'ies of slots to accommodate the successive sets of key and type levers provides for the proper hanging of' the key rlevers andthe supporting and guiding of the type levers in direct. contact therewith by 30 which their aliiieincnt and accurate operation is assured. When the key levers are hung upon the supporting flange they may be all secured. in posit-ifm by the locking piece extending above the top thereofl at a action of the bars upon their support while i the angle plate of the machine forms a posi- Ative pivotal sup ort for the slotted lower ends of the type e'versi lt will thus be seen that the invention presents a ty e bar movement adapted tobe formed of s feet material by a stamping or pressing operation .and one which is both efficient in operationand economical in construction. Having described m invention and set forth its merits, what. claiml and desire to secure by Letters Patent is 1.
